Effect Of Fiber Loading On The Mechanical Properties Of Bagasse Fiber–Reinforced Polypropylene Composites

It is evident that sugarcane/bagasse is a highly potential natural composite fiber. In this study, the correlation of composition fiber amount to the mechanical strength was presented. Bagasse was treated with alkali and then reinforced in polypropylene by means of hot pressing. Fiber loading was set to be varied from 10 to 20 wt%. Composite samples were subjected to tensile, hardness, and flexural characterization. Composites with 30 wt% of fiber loading registered maximum tensile strength while with 10 wt% fiber loading registered the minimum. Hardness increases with the amount of fiber. Flexural strength and flexural modulus were found to be greater than original polypropylene. Scanning electron microscopy examination revealed the mechanisms of the strength gain in morphological point of view. The findings give manufactures and engineers a sound basis decision whether to apply the use of this composite for weight reduction especially in automotive applications or not.

Development and mechanical characterization of green bamboo composites

In this study, a bamboo composite is developed using specific bamboo species known as Gigantochloa Scortechinii (Buluh Semantan) which can be found in Malaysia. In precise, the woven bamboo (WB) was formed from the culm fier composite with an average of 0.5 mm thickness and 5.0 mm width strip is laminated with Wowen E Glass (WEG) and reinforced with epoxy (EP). The laminated was using a hand lay-up technique. The developed bamboo composites are then characterized comprehensively in the term of tensile, hardness, impact, fatigue and fracture test. It is found that the strength was equivalent with the existing steel alloy in term of tensile and fracture properties.
